PetArmor Plus Flea and Tick Prevention for Cats, Cat Flea and Tick Treatment, 12 Doses, Waterproof Topical, Fast Acting, Cats Over 1.5 lbs
PetArmor Plus Flea and Tick Prevention for Cats is a topical treatment designed for cats weighing over 1.5 pounds and aged 8 weeks or older. It contains the active ingredients fipronil and (s)-methoprene, which work together to kill fleas, flea eggs, larvae, ticks, and chewing lice. One of its strong points is that it helps break the flea life cycle, which means it doesn't just kill adult fleas but also prevents new infestations by targeting eggs and larvae. The formula is waterproof and fast-acting, starting to work within 24 hours and providing protection for up to 30 days per application. The pack includes 12 doses, enough to cover a full year of monthly treatment. It’s easy to apply by parting the cat’s fur at the shoulder blades and squeezing on the drops. Because the product can leave a greasy residue for about two days, you might need to clean the area gently if it seems excessive.

Buying Guide for the Best Cat Flea And Tick Preventions
Choosing the right flea and tick prevention for your cat is crucial for their health and comfort. Fleas and ticks can cause a range of issues from mild irritation to serious diseases. When selecting a product, consider your cat's lifestyle, health status, and any specific needs they may have. It's important to understand the different types of preventions available and how they work to make an informed decision that best suits your cat's needs.Type of PreventionFlea and tick preventions come in various forms such as topical treatments, oral medications, collars, and shampoos. Topical treatments are applied directly to the cat's skin and are effective for a month. Oral medications are ingested and can provide protection for up to three months. Collars release active ingredients over time and can last for several months. Shampoos provide immediate relief but need to be used regularly. Choose the type based on your cat's tolerance and your convenience.
Active IngredientsThe active ingredients in flea and tick preventions are what kill or repel the pests. Common ingredients include fipronil, imidacloprid, and fluralaner. Each ingredient works differently and may target different stages of the flea or tick lifecycle. It's important to choose a product with ingredients that are safe for cats and effective against the specific pests in your area. Consult your vet to determine which active ingredients are best for your cat.
Duration of EffectivenessThe duration of effectiveness refers to how long the prevention will protect your cat from fleas and ticks. This can range from a few days with shampoos to several months with collars. Consider how often you are willing to reapply or administer the prevention. For busy pet owners, longer-lasting options like collars or oral medications might be more convenient.
Age and Weight RestrictionsMany flea and tick preventions have age and weight restrictions to ensure safety and effectiveness. Products are often formulated for specific age groups, such as kittens or adult cats, and weight ranges. Always check the product label to ensure it is appropriate for your cat's age and weight. Using a product not suited for your cat can lead to ineffective treatment or potential health risks.
Side Effects and SafetyAll flea and tick preventions have the potential for side effects, which can range from mild skin irritation to more serious reactions. It's important to read the product label and consult with your vet about any potential side effects, especially if your cat has a history of allergies or sensitivities. Choose a product with a good safety profile and monitor your cat for any adverse reactions after application.
Ease of ApplicationThe ease of application can vary significantly between different types of flea and tick preventions. Topical treatments and collars are generally easy to apply, while oral medications may require more effort if your cat is resistant to taking pills. Shampoos require regular bathing, which can be challenging if your cat dislikes water. Consider your cat's temperament and your ability to administer the treatment when choosing a product.
